SASH-LOCK.

Specification of Letters m Patented Oct. 13, 1914.

Application filed September 29, 1913. a Serial No. 792 469;

To all whom z'tmay concern: V I

Be it known that I, J AMES E. SHEPPARD, a citizen of the United States, residing at Colton, in the county of San Bernardino, State of California, have invented certain new and useful Improvements in Sash;

Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to sash locks and has for an object to provide an extremely simple and inexpensive device for locking the sashes of a window in any desired rela tive open positions.

A further object of the invention is to provide a sash lock which may be operated by manipulating a single lever and which will be strong and durable and will further be formed of a few parts that will not easily get out of order.

A still further object is to provide a shade carrier which may be adjusted in length to carry shades of various widths and which will in no way interfere with the operation of the sash lock.

With the above objects in view the invention consists of certain novel details of construction and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claim.

In the accompanying drawing illustrating this invention: Figure l is a front elevation of a window equipped with my improved sash lock and shade carrier. Fig. 2 is a view similar to Fig. 1 but showing the lock released to permit of the sashes being adjusted relatively to each other. Fig. 3 is a cross sectional view on the line 33 Fig. 1. Fig. 4; is a vertical sectional view on the line 4- 1 Fig. 1.

Referring now to the drawing in which like characters of reference designate similar parts, 10 designates a window casing, 11 the upper sash, and 12 the lower sash of a window. The sash lock comprises a rod 18 which extends vertically of the sashes and is bent inwardly at the upper end as shown at l i and secured to the center of the top rail of the upper sash, and extends down-v wardly below the top rail of the lower sash and is there bent outwardly to produce a grip 15. V l j Arranged on one side of the center of the top rail ofthe lower sash is an abutment plate 16 having an outstanding flange 17 which is provided witha pressed out groove 18 on the free edge. This groove embraces one side of the rod 13. Pivoted on the opposite side of the center of the top rail of the lowersash is a segmental cam 19 that is providedon its curved edge with an upstanding flange 20 having a pressed out groove 21 on the free edge which embraces the opposite side of the rod 13 and when the cam is in operative position clamps the rod firmly in the groove of the abutment plate wherebyboth sashes are locked by the rod against relative movement. a A link 22 is pivotally connected to the cam, on the opposite side of its pivot from the groove, this link extending outwardly along the top rail and is terminally equipped with a rubber tip 23, and when the cam is inoperative position the tip of this link bears against the inner face of the window casing and positively locks the lower sash against movement. There is a longitudinal slot 24: in'the link through which a pin 25 is passed into the top rail of the lower sash, the .linkrocking on this pin as a pivot when the cam is turned to inoperative position with a resultant withdrawal of the link from engagement with the window casing whereby the lower sash may be moved to any adjusted open position or to closed position. I

A handle lever 26 is secured to the cam at about thepivot -27 of the cam and forms means formanually rocking the cam to operative or released position.

In operation suppose that both the' upper. and the lower sashes are in partly opened position as shown in Fig. 1 and it is desired to open both sashes still further. The operatorgrasps the lever 26 and rocks the same with a resultant rocking of the cam 19 on its pivot to simultaneously release the rod 13 and link 22 whereupon the rod 13 maybe pulled downwardly and the lower sash then moved upwardly until they are in the desired relative open position whereuponthecam may be returned to initial position to lock the sashes in place.

From the above description it will be seen that I have provided an extremely simple and inexpensive attachment for windows which may be manufacturedat a minimum cost and will be formed of a few opposite side of said rod and serving to clamp said rod against said abutment plate, a link pivotally secured to said cam and J.
